Looking for books about puzzle design for games!
Hi everyone! I loveeee playing puzzle games of all kinds, as well as physical board games and puzzles like crosswords logic grids etc. I'm now developing my own detective game with its own puzzle system, i've done a lot of research by manually analysing games I've already played, but I want to read some stuff from professionals to get further insight into the design process!
Specifically I'm looking for books on game design that focus more on puzzles rather than general game mechanics! Blogs, articles or academic papers would also work!
